ABSTRACT:
A scene-pause counter, a scene-production counter, and a repetition counter are connected in a series. Each counter furnishes its count to an associated comparator which also receives a signal from an addressable read-only memory. Pulse trains are applied to the counters. When a comparator in the series detects coincidence, it initiates counting by the next counter. When the last comparator in the series detects coincidence it can restart the first counter. A program-selector switch causes different address signals to be applied to the memory, resulting in different operations of different durations, in different combinations and sequences. This makes possible projection or exposure of single frames or series of frames with intermediate pauses between the projection or exposure of successive frames or series of frames, as well as repetitions of such combinations of operations.
